FUEL-DISTRIBUTER FOR FURNACES.

Patented Aug. 22, rate.

Application filed January 12, 1912. Serial No. 670,858.

To all whom it may concern:

Be it known that I, CLEMENT F. STREET, a citizen of the United States, residing at Schenectady, in the county of Schenectady and State of New York, have invented new naces in which the fuel is fed through the wall; and another object is to provide an improved form of connection, having interlocking projections, between the parts whereby the flaring distributer end may be retained in its positoin by gravity and inclined at any desired angle,.and be readily detached and renewed when necessary.

In the accompanying drawings: Figure 1 is a plan of one form of my improved distributer, adapted to be used at the side of the furnace; Fig. 2, a side elevation of the same; Fig. 3, an end elevation of the detachable hood or end of the distributer; Fig. 4, a plan of a slightly modified form of my improved distributer adapted for use at the center or intermediate portion of the furnace; Fig. 5, a side elevation of the same; Fig. 6, an end elevation of the hood; and Fig. 7, an end view of the shank with the hood removed.

According to the construction shown 1 Figs. 1, 2, and 3, my improved. distributer notches or openings, 32, formed in the shank portion, and corresponding hook-shaped pro ectlons, 33, formed on the distributer end, these parts being adapted to interlock whereby the hood is retained in its position by gravity and both parts being provided with abutting flanges, 34 and 35, which restone upon the other, and support the distributer end at the desired elevation. By varying the angle of these engaging flanges, the distributer may be elevated at different angles of inclination to suit. any and all conditions of service.

For use as a side distributer, the detachable end,'23, may be formed as a broad flaring hood having a slightly curved under surface and short depending flanges, 25, at its side edges, and the bottom portion of the shank, 19, may be provided with a wedge shaped projection, 24, at its ends for diverting the fuel upward against the under face of the detachable hood. A flange, 30, may be formed on the elbow for engaging the front face of the the boiler shell.

As shown in Figs. 4 to 6 of the drawings, the distributer is of the same general construction, but the elbow, 20, with its shank portion, 20, is shown tapered, toward the bottom and provided with segmental ribs or flanges, 31, for fitting the cylindrical opening, 21, through the furnace wall of the boiler. This construction brings the side walls closer to the line of the fluid pressure blast, and is better adapted for handling finely divided fuel. The detachable distributer end or hood, 23*, as shown in this design, is'formed with flaring wings curved outward and downwardly to'a point below the end of the shank, the wings being divided by a curved central rib, 36. For the purpose of connecting this form of hood with the shank portion of the distributer, the latter is provided with side notches,'37, in the end flange, while the hood portion has projections, 38, for engaging in sald notches when the hood is slipped down over the end of the shank. The shank portion of the elbow may also be provided with an inside longitudinal rib, 40, arranged in line with the central rib, 36, of the hood.

By means of my improvement in which the distributer end or hood is separate and detachable from the other portion, said distributer end may be made of a different material, which is better adapted to withstand the excessive heat to which the same is subjected Within the furnace.

The distributer' end or hood may also be mounted at any desired angle of elevation and may be readily detached and renewed or replaced Whenever necessary or desired.

As the hood is retained in its place upon the end of theshank merely by its own weight, no tools or other parts are necessary in making renewals, the Worn out hood being simply lifted oil from the end of the shank, and the new one put in its place.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a mechanical stoker, the combination with a furnace wall having an opening, of an elbow outside the Wall provided with fuel and fluid pressure connections and having 20 an integral tubular shank extending through and closely fitting said opening, and a flaring distributing hood within the furnace, said hood and the end of said shank having interlocking notches and projections for de- 28 tachably connecting the hood with said shank and retaining the same in position by gravity.

In testimony whereof I have hereunto set my hand.
